DRM Patches For Linux 2.6.27 Kernel

Phoronix: DRM Patches For Linux 2.6.27 Kernel

The Linux 2.6.26 kernel had featured updated Intel and ATI DRM that added the needed kernel support for the ATI R500 and Intel GMA 4500 3D support. While the merge window for the Linux 2.6.27 kernel has already closed, we will hopefully see a few more Direct Rendering Manager (DRM) patches...

Yes, a good chunk of the DRM is GPU-specific and the proportion of GPU-specific code is growing as memory management and kernel modesetting are added. Dave Airlie recently re-organized the DRM source code to make it more like a typical kernel driver and to make the GPU-specific portions of the code easier to find and manage.

If you think of DRM as "the kernel driver for graphics" that will give you a pretty good understanding -- with the added complication that most of the same DRM code is also used with FreeBSD, Solaris and other OSes.
